Step-by-step explanation:

If the sound level of a jet plane is approximately 140 dB, the intensity of the sound of a jet plane is approximately 100dB

Sound level is the intensity to measure the sound. Decibels are used to quantify sound levels.

The sound level of a jet plane is expressed according to the expression given:

β = 10log(I/I0)

Given the following parameters

β = 140dB

I0 = 10^-12 W/m²

For required Intensity "I" Substitute:-

140 =10log(I/10^-12)

14 = log(I/10^-12)

10^14 = I/10^-12

I = 10^14 * 10^-12

I = 10^2

I = 100dB

Hence if  the sound level of a jet plane is approximately 140 dB, the intensity of the sound of a jet plane is approximately 100dB

Based on the seconds that Stoplight A and Stoplight B take to change color, the number of seconds till they change color at the same time is 30 seconds.

To find out the time that both stoplights will change color at the same time, you need to look for the lowest common multiple of 18 and 15.

The multiples of 15 are:

15, 30, 45, 60, 75, 90, 105

The multiples of 18 are:

18, 36, 54, 72, 90

The lowest common multiple is 90 seconds.

Because the lights changed color 60 seconds ago, the time till they change at the same time is:

There is no change in its slope as initial and final slope is 1.

What is slope?

In arithmetic, the slope or gradient of a line may be a variety that describes each the direction and therefore the abruptness of the line.

Main body:

formula for slope with two points form is =

y -y₁ =( y₂-y₁ /x₂-x₁ )(x - x₁)

according to question ,

points are (0,0) and (3,3)

y - 0 = (3-0/3-0)(x -0)

y = 3/3 *x

y = x

hence slope of line is 1.

Now points are (0,0) and (-3,-3).

y - 0 = (-3-0/-3-0)(x -0)

y =- 3/-3 *x

y = x

hence slope of line is 1.

So there is no change in its slope.

The reasoning presented lacks explicit explanations and logical connections between the steps, making it difficult to fully understand the intended proof strategy.

The given proof aims to show that the Separation Axioms can be derived from the Replacement Schema using a particular construction involving a formula p(x, y). Let's analyze the proof step by step:

Define the formula p(x, y) as x = yo(x).

This formula states that for each x, y pair, x is equal to the unique object y such that y is obtained by applying the operation o to x.

Define the set F as {(x, x) (x)}.

This set F contains pairs (x, x) where x is the unique object obtained by applying the operation (x) to x.

Claim: F(X) = {y (x = X)p(x, y)} = {y: (x = X)x = y^o(x)} = {x: (3x € X)o(x)} = {x X: (x)}.

This claim asserts that F(X) is equivalent to {y (x = X)p(x, y)}, which is further equivalent to {y: (x = X)x = y^o(x)}, and so on.

The proof states that since (x, y) satisfies the functional formula VaVyVz(p(x, y)^(x, z) y = z), it follows that (x, y) is a functional formula.This step emphasizes that the formula p(x, y) satisfies certain properties that make it a functional formula, which is relevant for the subsequent deductions.

Finally, the proof concludes that the Separation Axioms follow from the Replacement Schema, based on the previous steps.

Answer:

24% of $400,000 = 0.24 x $400,000 = $96,000

The amount he financed is:

$400,000 - $96,000 = $304,000

To calculate the total amount Roberto will pay for the house, we need to add up the principal (the amount he borrowed), the interest, and any fees or charges. We can use the formula for the monthly payment of a mortgage to find the total amount:

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1]

where M is the monthly payment, P is the principal, i is the monthly interest rate (6.2% divided by 12), and n is the total number of payments (30 years times 12 months per year).

Plugging in the values, we get:

$1861.91 = $304,000 [ 0.00516667(1 + 0.00516667)^360 ] / [ (1 + 0.00516667)^360 - 1]

Solving for P, we get:

P = $304,000

So the total amount Roberto will pay for the house is:

$96,000 (down payment) + $1861.91 x 360 (monthly payments for 30 years) = $96,000 + $670,287.60 = $766,287.60

Therefore, Roberto will pay a total of $766,287.60 for the $400,000 house.

The value of c in the polynomial is - 7.

The polynomial is given as follows:

p(x) = 2x³ - x² +  cx + 2 . The value of c if x - 2 is a factor of p(x) can be computed as follows:

Therefore,

p(x) = 2x³ - x² +  cx + 2

when x - 2 is a factor, p(x) = 0

Therefore,

0 = 2x³ - x² +  cx + 2

Hence,

2(2)³ - (2)² +  2c + 2 = 0

16 - 4 + 2c + 2 = 0

12 + 2 + 2c  = 0

2c = - 14

divide both sides by 2

c = - 14 / 2

c = - 7

During the morning rush hour, there are 6,400 junior and high school students, 3,400 adults, and 5,800 senior citizens riding the subway.

Let's assume the number of junior and high school students riding the subway during the morning rush hour is J, the number of adults is A, and the number of senior citizens is S.

From the given information, we can set up a system of equations based on the number of riders and the revenue generated.

Equation 1: J + A + S = 15,600 (total number of riders)

Equation 2: 1.04J + 2.20A + 1.04S = 32,464 (revenue equation with original ticket prices)

Equation 3: 1.24J + 2.60A + 1.04S = 38,264 (revenue equation with new ticket prices)

We can start by subtracting Equation 2 from Equation 3 to eliminate the J and S terms:

0.2J + 0.4A = 3,800

Next, we can multiply Equation 1 by 0.2 and subtract it from the above equation to eliminate the J term:

0.4A - 0.2J - 0.2A = 3,800 - 3,120

0.2A = 680

A = 680 / 0.2 = 3,400

Now, we can substitute the value of A back into Equation 1 to find the values of J and S:

J + 3,400 + S = 15,600

J + S = 15,600 - 3,400

J + S = 12,200

We have two equations with two variables (J + S = 12,200 and 1.04J + 1.04S = 12,264). By solving these equations simultaneously, we find J = 6,400 and S = 5,800.

Therefore, during the morning rush hour, there are 6,400 junior and high school students, 3,400 adults, and 5,800 senior citizens riding the subway.

To find the number of subway riders in each category, we set up a system of equations based on the total number of passengers and the total revenue. Solving this system will give us the number of junior and high school students, adults, and senior citizens. The number of riders doesn't change with the increase of ticket prices.

To solve this problem, we set up a system of equations based on the information given in the question.

Let's denote the number of junior and high school students as J, adults as A, and senior citizens as S. We know that there's total of 15,600 passengers, so:

J + A + S = 15,600

We also know that the total revenue was $32,464. Given the ticket prices for each group, we can write:

$1.04J + $2.20A + $1.04S = $32,464

Solving this system of equations (possibly with the help of a calculator or computer software), we can find the number of riders in each category.

The number of riders for each category would only change if the number of riders changes, not the price of the tickets, so when the prices increase, the number of riders remains the same.

F1 + F2 = ΣF' is the simultaneous equation that relates the two forces F1 and F2 in kilonewtons acting on a structure, based on the principle of equilibrium.

If two forces F1 and F2 in kilonewtons are acting on a structure, the simultaneous equation that relates the two forces can be derived using the principle of equilibrium. The principle of equilibrium states that for a structure to be in equilibrium, the sum of all the forces acting on it must be zero.

Mathematically, the principle of equilibrium can be expressed as:

ΣF = 0

where ΣF represents the sum of all the forces acting on the structure.

For the two forces F1 and F2, we can express their vector sum as:

F = F1 + F2

where F is the resultant force of the two forces.

Now, for the structure to be in equilibrium, the vector sum of the two forces must be equal and opposite to the vector sum of all the other forces acting on the structure. This can be expressed as:

-F = ΣF'

where ΣF' represents the sum of all the other forces acting on the structure.

Equating the two expressions for F and -F, we get:

F1 + F2 = ΣF'

This is the simultaneous equation that relates the two forces F1 and F2 in kilonewtons acting on a structure, based on the principle of equilibrium.
